7.62x54R non-corrosive?

Ammoman is selling spam cans of 7.62x54R from Russian and the description says this is non-corrosive. I assume this is older surplus, which may not be the case. Can anybody here tell from the pictures when this was manufactured and more importantly do you know when/if Russia changed to non-corrosive primers?

I already have a crate of what I assumed to be corrosive ammo for my Mosin but I sure wouldn't mind have a crate of non-corrosive if that is what this stuff really is.
